2-(1-b/2)=-b+37 eching

$$2 - ( 1 - \frac { b } { 2 } ) = - b + 37$$

b uchun yechish

$$b=24$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$4-2\left(1-\frac{b}{2}\right)=-2b+74$$

2b ni ikki tarafga qo’shing.

$$4-2\left(1-\frac{b}{2}\right)+2b=74$$

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$2\left(4-2\left(1-\frac{b}{2}\right)\right)+4b=148$$

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$4\left(4-2\left(1-\frac{b}{2}\right)\right)+8b=296$$

-2 ga 1-\frac{b}{2} ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$4\left(4-2+2\times \frac{b}{2}\right)+8b=296$$

2\times \frac{b}{2} ni yagona kasrga aylantiring.

$$4\left(4-2+\frac{2b}{2}\right)+8b=296$$

2 va 2 ni qisqartiring.

$$4\left(4-2+b\right)+8b=296$$

2 olish uchun 4 dan 2 ni ayirish.

$$4\left(2+b\right)+8b=296$$

4 ga 2+b ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$8+4b+8b=296$$

12b ni olish uchun 4b va 8b ni birlashtirish.

$$8+12b=296$$

Ikkala tarafdan 8 ni ayirish.

$$12b=296-8$$

288 olish uchun 296 dan 8 ni ayirish.

$$12b=288$$

Ikki tarafini 12 ga bo‘ling.

$$b=\frac{288}{12}$$

24 ni olish uchun 288 ni 12 ga bo‘ling.

$$b=24$$
